Does A Relay Need A Diode. They are sometimes called flywheel diodes, freewheeling diodes, relay diodes, or snubber diodes. This is useful for when you want to control a relay from things that can’t drive relays, like an arduino, or an integrated circuit from the 4000 series or 7400 series. A diode would not work in. below is a relay wiring diagram that shows how to use a relay switch with an npn transistor. the use of a flyback diode in a relay circuit prevents huge voltage spikes from arising when the power supply is disconnected. The transistor provides current gain, and a small input current can switch. In your circuit if you build it for real you'll see. a diode is put in parallel with a relay coil (with opposite polarity) to prevent damage to other components when the relay is turned off. you can easily make a relay driver circuit with a transistor, a current limiting resistor (to turn the transistor on and off), and. do all relays need a diode, no, not all, only about 90% of them do. the diode across the relay coil is there to prevent emf from the coil.
